LASTING-MACHINE.

Specification of Letters Patent.

Application filed May 8, 1911.

To all whom it may concern:

-particular utility when embodied in a lasting machine of a type illustrated in the United States Letters Patent to Grandy No.

552,834, dated January 7, 1896, although I contemplate the utilization of my improvements in any field for which they are adapt- An important object of my invention is to provide improved power actuated mechanism to accomplish certain arduous operations necessary in the lasting of shoes, which are usually accomplished by hand with undue demands upon the strength and attention of the operator, notably the stretching and crimping of the upper material over the toe and heel portions of the last.

Another important object of my invention is to provide mechanism for the manual actuation of these same device-s when for any reason it is not desired to use the power mechanism, and a cognate and highly important object of my invention is to relate these manually operated devlces to the power actuated mechanism in such fashion that the manually operated device may be used as means to control the operation of the power mechanism, with the result that whether the operator is using the power mechanism or performing the operations manually, he will in each instance operate the same controlling devices and will thus avoid the disturbing factor of a change from a familiar to an unfamiliar set of controlling devices.

a I tively the wipers and the last perpen A feature of the invention consists in the provision, 1n connectlon wlth wipers which .may be operated to work the upper into lasted position, of means for moving relaicular to the plane of the last bottom by power to compress the upper against the face of the toe portion of the last, together with means for augmenting manually the power compression of the upper. In the mechanism herein shown and described as embodying this feature of the invention, means is provided for actuating the wipers in a direction perpendicular to the face of the last bottom for the purpose of applying compacting pressure to the overlasted upper materials and means for controlling the'upward movement of the wipers and their return upon the shoe with upper compacting'force, the controlling means being so constructed and arranged that after the. power means has been set in operation said controlling means becomes effective upon further movement for supplementally operating the Wipers to further compact -'the upper materials manually.- Furthermore the power mechanism may come to rest with the work under pressure and when the mechanism is restarted means may be provided for relievingautomatically the pressure on the overlaid upper and for then backing off the wiper. In this way the outward drag caused by retracting the wiper, while it is still pressing vertically "upon the upper materials, is avoided.

Another important feature of the inven-' tion consists in means for effecting power actuation of the wipers to advance and'close them over the last bottom and controlling means, for example, a hand lever, is operatively connected with the power means, the controlling means being also arranged to become efiective during a portion of its operative movement to actuate the lasting devices manually. This arrangement may involve a lost motion connection of'the lever to the wipers to effect actuation of the wipers.

manually "and the power means may be in operation during the lost motion between the controlling lever and the wipers.

,As a further feature of the invention the controlling lever may be employed either to augment orto counteract manually the power actuation of the lasting devices. Furthermore the controlling lever is arranged to set the power means in operation and,

upon continued movementof the lever in the same direction, to actuate the wipers manually; This manual operation of the wipers is preferably in additlon to or supplemental to their power actuation-and is for the purpose of increasing the effect of the power actuation. of the lasting devices.

Y shown and described by way of illustration as applied to the toe rest of the lasting machine, a manually operated lever being pro vided for controlling the application of power to the'lbe rest, said lever being arranged for' continued movement in the same direction to actuate the jacking device manually. 1

In its preferred form my invention provides fluid-pressure mechanism to afford the means for actuating by power the several devices for performing the operations forming the'subject matter of this application, and handles and treadles are provided in appropriate places for operation by the hands and feet of the operator, these handles and treadles being connectedwith and arranged to operate valves governing the application of the fluid-pressure to cylinders constructed and arranged to actuate the lasting devices, including in that expression broadly any de-, vice in the machine thus actuated. In numerous respects, however, my invention is not limited to the nature of the power operating mechanism but is broad enough to include, and the claims are to be so interpreted vwhenever their terms permit of such a construction, any power operated mechanism for causing the lasting instrumentalities to do their work.

Among still other notable features of my invention may be mentioned the provision of means by which the fluid in the power cylinders is utilized as a check or retarding medium for certain portions of the mechanism including a spring in which power is stored, particularly for use in the operation of the tacking mechanism, this check operating in place of, or as an auxiliary to, the fluid chock heretofore provided by me for lasting machines of this type, and which is illustrated and described in United States Letters Patent 1,018,477, granted to me Feb'. 27,1912.

I have provided also for means by which the power exerted by the fluid under pressure may be in certain operations offset in part or in whole manually, so that in such an operation as that of stretching the upper material'over the toe, for example, the operator can exert a countervailing action in opposition to the fluid pressure, thus afi'ording the possibility of very delicate gradation of the force applied to the material at various stages in its treatment, the latter purpose, in general, being an outstanding characteristic of the respective objects herein enumerated.

The various features of my invention will be illustrated and described fully in the accompanying drawings and specification, and pointed out in the claims.

In the drawings, Figure 1 is a view in front elevation of a lasting machine in the construction of which my invention has been embodied; Fig. 2 is a fragmentary detail view in plan, upon an enlarged scale, of the toe lasting mechanism of the machine shown in Fig. 1; Fig. 3 is a view in vertical section-on the line w w Fig. 1, looking from right to left, parts being shown in,elevation, and other parts omitted or broken away for the sake of clearness in illustration; and Fig. 4 is a perspective view of parts shown in Fig. 3.

In the embodiment of my invention selected for illustration and description, to enable ready and complete understanding of my improvements, the part designated by, thereference numeral 1 is the bed ofa lasting machine, which may be of any suitable construction and as one convenient form of such construction is provided with a base or frame comprising standards 2 and crosspieces 21, the bed serving as a support for heads, blocks or frames 3 and4 upon which are supported the lasting devices for the toe and heel parts respectively; the bed supportfmg also the jacking devices comprising 20 which serve to give the proper direction to the wiper device 8 and 10- in their wiping action when actuated thereto by suitable means which in the instance illustrated comprises a pair of links 24 connected to a bar 26, the links being preferably connected pivotally to the carriers 12 and 14 respectively as at 28, and the toe lasting devices in combination being supported preferably by a suitable cradle 30, all of which may be as illustrated and described in the aforesaid Patent No. 552,834. As disclosed in said patent the cradle 30 may conveniently be mounted pivotally as at 32 (see Fig. 1) to permit rocking movement of the cradle and the toe lasting devices about a horizontal axis extending transversely of the machine from front to rear under the control of a suitable device such as the crank-handle 34 operating a screw 36 having a suitable bearing on a slide or table 38 which forms part of the head-block 3 carrying the toe accommodate the roll.of the last, and for :this purpose the lasting devices are shown ,as mounted "upona sleeve 57 (see Fig, 2 which extends ipreafierably along the longiltudinal axis of the machine, at e sleeve v57 derives its support from bed blocks 52 secured :by suitable means such as-the bolts 54 upon the cradle 30, and $0 regulate this tilting movement positively I have shown .a-

screw shaft 56 engaged with acollar 58 and actuated by a handle '60. Ilhe above parts also are substantially .as shown and described in. said Patent No. 552,834, the rod being connected .to the equalizing bar 26, and serving when actuated co-axlally by suitable means :to force the equalizing bar iforrward and drive the wipers 1nto shearing engagement with the toe of the shoe, in a manner well understood to those skilled 1n the art, and which need not'be detailedherein as it constitutes-no part of my -,present invention.

ZEn accordance with my invention, I pro vide suitable power mechanism to actuate the wipers 8 and- 10, and such actuating "means may be of any suitable construction.

As one convenient form of device for this urpose, .l have shown a fluid pressure cylinder 70, constructed and arranged to re- .ceive a piston 72 mountcd'upon the rod 50 near its end, the cylinder being mounted upon a suitable support such as the yoke 74 bolted at 76 and .78 to'the bed :block of the cradle with which the cylinder may turn when the cradle is oscillated laterally by the handle 60, the cylinder rising and falling also with the cradle in its movements: about the horizontal axis 32 under the ac- 1 tion of the handle 34, already described.

To operate the cylinder any suitable medium may be employed, and I have; shown as one-convenient form of operating means an inlet tube 80 leading from the cylinder to a suitable source of fluid under pressuresuch as the stand pipe 82, vprovided with a weighted piston 84, an outlet or return pipe 86 being also provided preferably leading from the cylinder 70 to a pump 88 driven by a motor 90 from which the fluid is forced through the conduit 92 and stored again under the pressure in the stand To control the operation of the piston 72 .in the cylinder 70, by regulation of the introduction to the cylinder of the fluid under pressure any suitable means may be provided, and as one convenient form of device for this purpose, I have shown a 8-way -valve 94 operated by a hand lever 96, and

of rod 98 isipositively engaged by the stud 99 for manual actuation of the rod 50. If for any reasonv manual operation is tobe substituted for operation by fluid pressure or is to be used to supplement the power operation the movement of the handle 96 continuously in the ordinary direction of its movement for pperation of the valve 94 will result in manual actuation of the toelasting devices 8 and 10. If found desirable, suitable means may be provided to move the rod- 50 in reverse direction for the purpose of opening the toe-wiping devices, and any suitable means may be provided for this purpose, one-convenient form of such means being constituted ,by the spring 102, Fig. 2, Within the cylinder 70, and if desired the bolt and slot connection 98-j99 may be so arranged that when the handle 96 is reversed, the same movement which closes the inlet and opens the outlet will, if continued, enable the operator to withdraw the rod 50 positively leftwardly and open the wipers 8 and '10.

Similarly, in accordance with my invention, the actuation of the heel lasting devices carried by the head 4 may be rovided for by running an inlet conduit 10A and an outlet conduit 106 from the stand pipe 82 and pump 88 respectively to va cylinder 170 having a piston 172 connected operatively with a rod 150 which in turn is connected actuatively with heel wiping devices 108, the latter being mounted upon a cradle 130, mounted upon a transverse horizontal axis 132 upon the head 4, a hand crank 134 serving to rock the plane of the -I wipers about the axis 132 while a hand crank 160 serves to tilt the cradle 130 and heel wipers 108 about the longitudinal axis of the rod 150. The reference numeral 7 designates a table mounted pivotally at 9 upon the bed 1., and swinging atfits rear end upon a track 11 the table carrying the head 4 upon suitableways 13 along which the head 4 may be moved by the hand-wheel 15. The reference numeral 17 designates a hand-crank to adjust limiting stops for the swinging movements of the table.

The parts described in the foregoing paragraph may be, and preferably are, all substantially the same in construction and operation as similar parts described in my above mentioned Patent No. 1,018,477, with the exception of the fluid pressure cylinder and its connections, for the control of which I have shown a handle 196 operating a valve, similar in construction and operation to the handle 96 and valve 94 already described herein with respect to the toe lasting devices The numeral 203 designates a spring to return the rod 150 and wipers 108 to their normally open, inoperative position.

The handle 196 may be used to actuate the rod 150 and wipers 108 manually in a fashion similar to that described with reference to the valve lever 96.

In a machine of this character it is customary to provide for raising and lowering the heel post 6, and suitable mechanism may be provided if desired for accomplishing such movement by fluid pressure or power, but as very little power is required for this purpose, I have not shown fiuidpressure mechanism to accomplish the same and have merely indicated the machine illustrated as provided with one convenient form of treadle 61 for the above purpose, the lever being mounted upon a stud 63 on one of the frame uprights 2, and having a connecting rod 65 running to a bell-crank lever 67 carried upon a shaft 69 in brackets 71 depending fro-m the bed 1, suitable connections, not

shown, leading from the bell crank 67 to the heel post 6, preferably as detailed in my aforesaid Patent No. 1,018,477, the specific form of mechanism for raising and lowering the heel post forming no part of my present invention. So, also, the raising and lowering of the toe support5 may be accomplished by any suitable mechanism, such as that illustrated in full detail and described at length in my aforesaid Patent No. 1,018,477, and which need not be illustrated in detail in the present application, in which it will be suilicient for a proper understanding of my present invention to note that the mechanism for raising and lowering the toe support includes a rod 81 which, as may be seen most readily by reference to Fig. 3 is connected at 83 with a disk 85, carrying a pawl 87 to be engaged with the teeth of a ratchet wheel 89 mounted rotatably upon a cam shaft 91 carried in suitable bearings upon the bed 1, and this cam shaft 91 when rotated serves to perform certain operations detailed in my aforesaid patent, including the raising of the toe support 5. In accordance with an important feature of my invention, I prefer to actuate the ratchet wheel 89, pawl 87 and rod 81 by power, as the rod 81 is operated frequently and it is desirable to relieve the operator ordinarily of the necessity for applying manually to it the power necessary to accomplish its actuation.

Any suitable power device may be provided to actuate the rod 81, and as one con- 'end of which is connected to a treadle 109,

depression of the treadle serving to open the valve 127 and admit fluid under pressure to the cylinder 97, a spring 111 serving to close the valve, by raising the valve operating slide 129 and treadle 109 when the latter is released. In order to permit manual actuation of the rod 81, in accordance with my invention, any suitable device may be provided, and as one convenient form of such mechanism, I have shown the treadle 109 as mounted upon a stud 113 carried by the frame member 33, the treadle 109 having an arm 115 extending into position to engage at times with a stud 117 carried by a lever 119 which isalso fulcrumed upon the stud 113, the lever 119 being connected at 121 with a slide 123 which is also connected at 125 with the rods 93 and 81. The arm 115 is so proportioned that when the treadle 109 is depressed, ordinarily, the valve 127 will be opened and fluid pressure will be released to operate the piston 95 and rods 93 and 81,, before the operator exerts any considerable manual pressure upon the lever 119 through the arm 115 and stud 117. If for any reason the fluid pressure is not in operation a simple continued downward pressure by the operator upon the treadle 109 will engage the arm 115 with the stud 117 and will operate the lever 119 to draw down the slide 123 and rods 93 and 81, thus operating the ratchet wheel 89. A spring 135 may be provided to return the rod 81 to its normal position shown in Fig. 3. y

The lever 119 is utilized to windup a spring 146 to store energy therein for the operation of the tack feeding mechanism of a hand-tacker used in the lasting operation, and which I will now describe briefly, referring to my aforesaid -Patent No. 1,018,477 for a more detailed description of this mechanism, the details of which form no part of my present invention. For purposes of my present description it is sufficient to say that when the lever 119 is operated it forces upward a rack-bar 142 through the medium of a-link 140, and rotates a shaft 144 to wind up the spring 146, the latter operating by suitable connections through a belt 162 to rotate the tack feeding mechanism 164 by which the tacks are passed to the hand tacking device 168, and

when the lever 119 is released the descent of the rack-bar 142 under the action of the spring 146 is retarded by suitable means which in the instance illustrated may comprise the fluid above the piston 95 in the cylinder 97, together with the. weight of the piston rod 93, connectingrod 81 and slide 123. At times when the fluid is not present in the cylinder 97 I may, as an auxiliary check for the rack-bar 142, retain the checking device illustrated in Fig. 3, and. described more at length in my aforesaid patent, as comprising a piston 151 operating in a cylinder 152 containing fluid, which maybe introduced into a reservoir 154 and controlled by a thumb-screw 155. When there is fluid present in the cylinder 97, the thumb-screw 155 may be opened to permit free operation of the piston 151 and rack-bar 142.

In accordance with another important feature of my invention the mechanism for raising and lowering the head 3 may, and preferably will, be actuated by power to accomplish' the operation of stretching the uppermaterial over the toe, and for this purpose I have shown the connecting rod 250 by which this is accomplished as provided with a piston 272 entering a cylinder 270 carried by one of the frame uprights 2, this cylinder having an inlet conduit 280 and an outlet conduit 286 leading from the standpipe 82 and to the pump 88 respectively, a three-way valve 294 serving to regulate the flow of fluid, under the control'of suitable means such as the crank 296, actuated by a rod 298 running to a treadle 299, which may and, in accordance with a valuable feature of my invention, preferably will have a slotted rod 302 connecting by headed stud 312 the treadle with the member 250 for manual actuation of the latter by the continued movement of the treadle. By adjustment of the nuts 300 on the rod 298,

the operation of the valve 294 can be timed in advance of the upward actuation of the link 3302' by the treadle 299, so that resort need only be had to manual uplift of the head 3 in the absence of or in addition to fluid under pressure. A spring 303 may be provided to return the parts to the normal position shown in Fig. 1. The treadle 299 and slotted rod 302 may serve also to enable the operator to exert a more sensitive check upon the power applied to working upon the shoe, for by bearing down with his heel upon the heel of the treadle 299 the operator can counteract the fluid pressure.

Having illustrated and described my invention thus fully, and suitable means for carrying the same into eflfect, I wish it to be understood that I do not limit-myself to the specific construction and materials selected for illustration and description by way of example, nor in general do I limit myself otherwise than as set forth in the claims read in connection with this specification.
